[00:00:00]People in places with heavy parasite loads tend to die early. They don't get old enough to have cancer, which is why the cancer rates in West Africa are so low. They're under 1/3 of what they are here in the United States. Biggest driver, the single biggest driver of cancer worldwide isn't pollution, it isn't even genetics, it's age. It's age.
